Title: Clock switching device
Inventor: OTSUKI KOICHI
IPC: G06F1/08
Filed: 1989-10-11
Abstract: PURPOSE:To reduce the deformation of a clock waveform and the jitters by connecting the outputs of tristate buffers contained in plural oscillators having different frequencies via the logic of a wired OR. CONSTITUTION:The tristate buffers 101, 111 and 112 are used as the clock switching output stages of oscillators 1-3 (106-108) and produce the high impedance states. That is, the oscillators 106-108 serve as the outputs 101, 111 and 112 of the tristates and selected by the selection signals 106-108 to produce the signals 113-115 respectively. When the oscillators 106-108 are not selected, the outputs 101-112 are set at high impedances and these oscillators are isolated from other circuits. As a result, no adverse influence is given to the waveform of a selected clock. Then the deformation and the jitters of the clock waveform are reduced.

Title: Data recording system
Inventor: ADACHI OSAMU
IPC: G11B20/12
Filed: 1984-12-17
Abstract: PURPOSE:To improve the reliability of detection of a sector synchronizing signal sharply by arranging plural sector synchronizing signals in a preamble. CONSTITUTION:Preamble PA1 is constituted so that sector synchronizing signals SS and bit synchronizing signals BS1 having a prescribed bit length are arranged repeatedly by the prescribed number of times. In a preformat area PF having the preamble PA1, a signal generator generates a signal in accordance with the format. When a sector synchronizing signal SS is incorrectly detected at a time t2, no sector synchronizing signal SS exists in a time t3 when a detecting window is formed after a distance L, so that the operation is turned to a synchronization detecting mode in which no window is formed at that time. Consequently, the succeeding sector synchronizing signal can be detected, so that the influence of the misdetection can be removed.

Abstract: PURPOSE:To prevent residues on the surface of a specimen after the removal of a resist by a method wherein the ashing and removal temperature of a hardened resist used as a mask for an ion implantation operation is set to be not higher than the postbaking temperature of the resist before the ion implantation operation. CONSTITUTION:The surface of a wafer 1 is coated with a resist 2; a postbaking operation is executed at 160 deg.C; after that, an ion implantation operation is executed; a resist removal operation is executed at 150 deg.C. When the removal treatment of the resist is executed at a temperature which is lower than the temperature of the postbaking operation in this manner, it is possible to prevent that the resist is pyrolyzed more than in the postbaking operation when the resist is removed. Since it is possible to eliminate that the resist is pyrolyzed in the removal treatment as a cause to generate air bubbles, it is possible to reduce residues which are left at the edge of the air bubbles.

Abstract: PROBLEM TO BE SOLVED: To obtain a current-limiting element, provided with a long current path by forming it from an oxide of a specific composition of superconducting substances and providing it with a structure of laminated plates having two-dimensional meandering structure. SOLUTION: Plates made of REBa2 Cu3 Ox bulk superconductor are laminated with equal narrow gaps in-between, and are coupled with one another to form an element structure. Cuts 4 are formed in the superconductor plates 3, and the adjoining plates are coupled with each other at their corner 5. There are small gaps 6 between the plates. Thereby superconducting materials having long current paths can be manufactured from superconductor bulks with a limited shape. The melting method is as follows: temperature is increased to a temperature range in which a RE2 BaCuO5 phase is present, together with a liquid phase composed mainly of Ba-Cu-O. Then the temperature is reduced to a value immediately above a peritectic point at which REBa2 Cu3 Ox is produced, and the temperature is gradually reduced for growing a crystal. Thereby large crystal grains are obtained.

Abstract: PURPOSE:To make uniform the depth of the pressure reference chamber of a pressure sensor between the sensor and a chip by a method wherein the pressure sensor is formed into a constitution wherein an oxide film is formed on a silicon substrate and a polycrystalline silicon film is formed thereon. CONSTITUTION:An oxide film 2 is formed on a silicon substrate 1 using a crystal face as its main plane by a thermal oxidation, an oxide film 2a, which is one part of the film 2, is removed by patterning to form a polycrystalline silicon film 3 on the film 2 by a CVD method and an oxide film 4 is further formed thereon by a CVD method to pattern the film 4. When the silicon film 3 is etched using the film 4 as a mask, the film 2 formed on the upper surface of the substrate 1 appears, but as there is a difference of 15:1 between an etching rate in the silicon film and an etching rate in the oxide film 2, the progress of an etching on the oxide film becomes slow. Accordingly, when the film 2 and 4 are removed with a solution prepared in the ratio of an ammonium fluoride : a hydrofluoric acid = 10:9, the depth of a pressure reference chamber 5 can be formed and a pressure sensor having little irregularity in sensor-chip characteristics can be attained.

Title: Temperature controller for heating and fixing device
Inventor: MORI SHIGENORI
IPC: G05D23/19
Filed: 1987-10-22
Abstract: PURPOSE:To prevent an extreme overshoot by bringing a heater to ON/OFF operation by setting a set temperature as a fixed control target temperature after a control target temperature is reached the set temperature. CONSTITUTION:When a temperature detecting means 3 detects a surface temperature of a heating roller 1 after cycle-out, a predictive target temperature determining means 4 determines a predictive target temperature being below a set temperature based on its temperature information, and until a response temperature of the temperature detecting means 3 reaches the predictive target temperature, a heater 2 is brought to ON operation by the first heater driving means 5. In this case, the surface temperature of the heating roller 1 reaches about the vicinity of the set temperature. Thereafter, when a control target temperature setting means 6 increases gradually and sets control target temperature between the predictive target temperature and the set temperature, whenever the response temperature of the temperature detecting means reaches each control target temperature, the heater 2 is brought to ON/OFF operation by the second heater driving means 7. Subsequently, when the control target temperature reaches the set temperature, the third heater driving means 8 brings the heater 2 to ON/OFF control by setting the set temperature as the fixed control target temperature. In such a way, an overshoot is prevented.

Abstract: PURPOSE:To improve bistability of a liquid crystal molecule and to obtain superior display characteristic by regulating the electric conductivity (rho) of orientation film to below 1X10<8>OMEGAcm. CONSTITUTION:Electric conductivity (rho) of at least one orientation film 13 contacting with a liquid crystal layer 18 is regulated to below 1X10<8>OMEGAcm. A preferred method for regulating the electric conductivity (rho) of the orientation film 13 to below 1X10<8>OMEGAcm is to form orientation film by adding a suitable electroconductive material to a resinous material which has been used conventionally as orientation film in the stage for forming the orientation film 13. Suitable material for forming the orientation film 13 is selected from, for example, polyvinyl alcohol, polyimide, etc. By this method, uneven distribution of ions in the liquid crystal layer 18 and adverse effect derived therefrom are eliminated. Moreover, the bistability of liquid crystal molecules 16, 17, is improved by relaxing the internal electric field due to polarization of the liquid crystal molecules 16, 17. Thus, the switching characteristics, etc. is improved.
